IMPROVED NAIL-PLATE FEEDER.

TO ALL WHOM IT MAY GONCERN: .f

Be it known that I, CYRUSD, HUNT, ofFair Havengin the'county of Bristol, and State of Massachusetts, have invented a new and vuse'ulImprovement in Cut-Nail-Plate Feeder; andl do herebyzdeclare that the following is afull, clear, and exact description thereof,'which will enable those skilled/,inthe art to make and use the-same, reference being had to the accompanying drawings, forming partrofthis speciiication.

Figure l represents a side elevation of my improved cut-nailfplate feeding-apparatus as. attached to a nailcutting machine.

:Figure 3 represents a modification of a detail.

'Similar letters of reference indicate corresponding parts. l

This invention relates to'a new and useful improvement in feeding-apparatus for turning or reversing and feeding nail-plates in a nail-cutting machine automatically. y

This improvement consists in a cylinder, through which pass the nipper-rod` and nail-plate, which are reversed by an oscillating motion given to the cylinder by a pin or friction-roll working in a double or rightand-,left spiral slot, groove, or ange, on the side of the cylinder, while,at the same time, the operation of feeding the nail-plate is-performed by means of rods, levers, springs, and clasps,on-the nipper-rod, as hereinafter minutely described. t l v A represents the support for the cylinder-rest ;,a a are two screws for supporting Vthe cylinder-rest, and admitting of movement around a. `pointfon line drawn through the same as a-centre, a's shown in iig. 3; B represents the cylinder-rest; C represents the cylinder; c c are spiral slots or grooves in the cylinder; D, a piu or friction-roll to it in the grooves c ct, and attached to the machine; E represents the feed-rest, attached to the cylinder-rest; F represents the feed-lever; ff aretwo catches on the feed-lever VGr 'represents the spring 'Y set against the feed-lever F to throw it forward; g is a spring to overcome the power of the spring G; II is thefeed-rod; Iis the nipper-rod,whichis a screw with nipp'ers lor clamp -on the end to hold the nail-plate, the

thread'being cut so as lto allow the catches ff to move the ,same forward; J represents the connecting or driving rod; jj, two gear-wheels; M is the nail-plate; m, a standard for the pin or roll D; n, a pin onconnecting-rod J s s are catch-springs. Y. e v A The support A is attached to the machine by one or more screws, andis connected withV the cylinder-rest I3 by a hinge-joint or it may better befconnected by projecting ears, with' two 'set-screws, a a, acting as centres to support the cylinder-rest, and also to adjust the nai1plate by moving the same, as shown in red lines in iig. 3. The cylinder-rest B, being thus supported, can be 'easily turned on the screws a a to andfrom 'the machine, or can be turned down entirely out of the way of the cutting-knives, when the same require adjusting, by dis'- connecting the pin D and driving-rod J. l

' The cylinder (lrbeing supported by one or two bearings (as circumstances may require) on the rest, can be easily turned'or rotated on its bearings. A` i I The cylinder C. has a spiral slot on one side, or a, ange or groove, which runs one-quarter around the' cyli `inder, when it turns and runs nearly at right angles another quarter around the cylinder, till it has described one-half of `the cylinder in the form of right-andleft screw-cuts. Into these slots, c c', -a pin or frictioneroll, D,

is inserted, and firmly attached to the bed of the machinerby a standard, m. I

Attached to the cylinder-rest is the feed-rest E, in which is 'the feed-lever F, which is moved forward byl the spring G.

Y On the top of the feed-lever F are two catches, f f, against which press two springs, e s.. to make them claspI the nipper-rod I.

Leading from the spring G to the spring g is`a rod, so set as to allow the stiter spring g to overcome and throw back the lever F. The rod H is carried forward to strike against the bed-piec ofthe machine just beforethe cylinder-rest with its attachments has reached the maximum pointforward, thus pressing back the spring g, and allowing the full power of the 'springG to act against and throw forward the lever F, which, by the action of the catches ff in the thread of the nipper-rod I, throws forward with the torceot the spring G.

The driving-rod J is connected with the gear-Wheel j by a. crank-pin, set out of the centre a. sullicient distance to give the required movement, and is also attached to a. pin or bolt, n, in the cylinder-rest.

As the machine tnrns, the rod Jthrows back theA cylinder, which is .made to rotate one-quarter by the pinl or friction-.roll D, playingin the grooves c c'. -The .feed-rod H relaxes its pressure on the spring g, which over comes 'the spring Gr, and the feed-leverli` falls back for the catches ff t'o slip back on the nipper-rod I.

With themachine in motion, at its ordinary speed, the momentum'of the cylinder B carries it over the centre point of the grooves c c; and, as .the cylinder C is drawn forward, the pin or friction-roll causes the cylinder to rotate the other quarter, 'thus completing the inversion" of the nail-plate in the cylinder. As itis carried forward,vtlie feed-rod H strikes the bed-piece, throwing back the spring-g, which thus permits'the force of the'spring G to throiv forv'fard thelever vF-,v\vhich', by the4 catches fl'carries forward the nipper-rod I, and

the nail-plate M is this forced between thc 'cutting-knives, against the gauge, with the power of the spring G. After the blank for the nail is cut from the plate, the cylinder-rest end all its attachments are thrown back,

and the cylinder with the plate @goin inverted, as before described.' I A Having thus deseribed'my' invention, I claim as new, and desire to secure vby Letters Patent* W The method of feeding the nail-plate by means of the hinged rest B,vfeed-restlE, feed-rod-I-l, the springs G g, the lever F, 4the catches ff, and the Dipper-rod I, constructed and operating substntially l11's, described.
